Thank you all for the advice! Im not insistent upon Dervish, in fact Dervish doesnt really suit my playstyle well. I like to hit and run, using hard-hitting skills frequently as opposed to normal attacking. I found a Purifier build that seems to be exactly what Im looking for ([1.1.4.2] Ulzuin's Barrelsmith - Skyfire grenadier reborn (6min buffed/bannered clear; 9min naked)), but if Im correct, it would appear to be an item-dependant build. If it is item-dependant, how difficult/time consuming would it be to collect all the pieces?
